Properties of entanglement in a Spin Chain with impurities
(2012-11-09)
In this thesis we have studied the e®ects on ground-state entanglement and
quantum-state transfer caused by the presence of one and two diagonal impu-
rities in a 1D ring-shaped spin-1
2 hamiltonian with XX ferromagnetic ...
Diffusion and implantation of dopants in single-wall carbon nanotubes:a spectroscopic investigation of chemical and electronic properties
(2012-11-09)
Raman measurements, performed on MWCNTs grown by arc discharge
method in He atmosphere, have pointed out the occurrence of a band at 1780-
1860 cm–1, regardless of the use of a catalytic Ni-Cr alloy in the synthesis ...
Three-Dimensional Hybrid Code for Earth's Magnetotail Dymamics
(2012-11-08)
This work is dedicated to the development and exploitation of a new threedimensional
(3D) particle code for equilibrium plasma con gurations. The
code is of the so-called hybrid type, that is ions are treated as particles ...
Optical systems for diagnostics: Near-Infrared Imaging technique for detection of dental demineralisation
(2012-11-30)
In dentistry, a correct detection of caries severity is still a challenging
descision-making task that crucially a ects the choice for the best treatment
plan. The challenge is to nd both the most objective parameters ...
Optical trapping and manipulation exploiting liquid crystalline systems
(2012-11-30)
This thesis and all the research contained within, pretends to develop new ideas
and concepts on liquid crystals (LC) and optical trapping and manipulation. The
combination between optical tweezers and LC systems promises ...
